Power Window Wiring....Routing - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**spudder** · 01-22-2021, 11:32 AM

I'm planning to add OEM power windows to an '04 GMC 1500. After researching the net, my best bet is to use the wiring out of a '99-'02 truck. This will avoid all the BCM issues that relate to power window operation on '03-'07 trucks. As I understand it, using the earlier harness requires only an ignition power wire and a ground wire to complete the window wiring.
I want to know where the window wiring harness runs across the truck to the passenger side and where it exits the cab.
Has anyone done this swap? Any help appreciated.
